Interface JavaWildcardType

All Superinterfaces:

Element, JavaElement, JavaHasAnnotations, JavaHasName, JavaHasType, JavaIsGeneric, JavaMember, JavaType

public interface JavaWildcardType

extends JavaType

The WildcardType is a new concept in jdk 1.5. A WildcardType has a superclass and possibly one super-interface. A WildcardType declares no fields, methods, constructors, or inner classes. If no superclass was declared, then java/lang/Object is the implicit superclass. Because wildcard types have a superclass and possible a super-interface, of super-interfaces, they may have hierarchies.

Wildcard types are not interface, enum, annotation, primitive, or array types. Note that a WildcardType does not have a proper name and "?" will be returned for its name, qualified name, and raw name.

Intersection types are represented as wildcard types.

Method Detail

getUpperBounds

java.util.Collection<JavaType> getUpperBounds()

Upper bounds are "extends" bounds.

Returns:

The upper (inclusive) bounds, if any. Must be a reference type. Collection of JavaType's.

getLowerBounds

java.util.Collection<JavaType> getLowerBounds()

Lower bounds are "super" bounds.

Returns:

The lower (inclusive) bounds. Empty if none. If non-empty, all bounds must be reference types. Collection of JavaType's.

Note: This is not like java/lang/reflect/WildcardType which returns the primitive type "null" if no lower bound was declared.
